A Chevron osteotomy is a commonly done surgical procedure to deal with bunions on the foot. The bunion is the swelling and a misalignment of the big toe which causes the big toe to turn towards the smaller toes.

Each of the surgeries carries a number of indicators as to who it can be the best option for. Using a Chevron osteotomy, the feet and ankle orthopaedic as well as podiatric physician cuts a “V” at the end of the long bone behind the great toe (the first metatarsal) and then revolves that cut portion of the metatarsal to push back the great toe.

These researchers reported that the range of flexibility of the great toe joint reduced between the initial examination and the two year follow-up however was no worse at 5 years. In addition, they documented no alterations in the angle of the hallux valgus deviation between the 2 year and 5 year evaluations. Those over the age of fifty years did as well as more youthful individuals which puts a question mark on the Chevron osteotomy predominantly getting indicated for younger individuals. The Chevron osteotomy surgery might harm the blood vessels close to the bottom of the great toe, however these authors uncovered zero cases of osteonecrosis with the metatarsal head at either the 2 year or 5 year follow-ups time frames. Nevertheless, they did find that there was osteoarthritis of the big toe joint joint in 8 feet at the 2 year review and in 11 feet at five yr review.

Just like any surgical treatment for a bunion, the Chevron osteotomy is an excellent alternative for the right indicators and when performed by a surgeon who is acquainted with those indications as well as contraindications and possesses the technical competencies to accomplish the procedure diligently.
